' ICE-SCORING MACHINE.

Application filed August 13, 1924, Seriallio. 731,834.

To all toil-om it may concern:

Be it known that we, J ()SEPH :STRIHENSON' YAGER and L nn STARLING,citizens of the United States, and residents of Greenville, in thecounty of Washington and State of Mississippi, have invented certain newand useful Improvements in Ice-Scoring Machines, of which the followingis a specification.

This invention relates to ice scoring machines and has for its objectthe provision of a device which is adapted to provide a horizontal outand vertical cuts upon opposite faces of a block of ice whereby the icemay be readily chopped in the usual manner for producing blocks of iceof uniform dimensions.

A further object of the invention is the provision of an ice scoringmachine having a movable carrier and carrying saws for causing verticalscores on a block of ice and in which thecarriage automatically andthrough its own weight is caused to descend for-causing the saws toscore the ice.

A further object of the invention is the provision of a device having amovable carriage carrying; vertical scoring implements and stationaryhorizontal scoring iinpl inents adapted to cause horizontal scores inadvance of the vertical scores and which are caused to be operated whenthe carriage is at its most elevated position.

This invention will be best understood from a consideration of thefollowing detailed description, in view of the acoompanying drawingforming a part of the specification; nevertheless it is to he understoodhat the invention is not confined to the disclosure,r,being susceptibleof such changes and modifications which shall define no materialdeparture'fi'oin the salient features of the invention as expressed inthe appended claims.

In the drawings:

Figure l is a side elevation of the ice scoring machine.

Figure 2 is an end elevation of the same.

Figure 3 is an end elevation of the ice scoring machine where the iceenters the same.

Figure l is a view in perspective of the scoring device with thesupporting frameworlr eliminated.

Figure 5 shows a block 03"; ice which has been scored by the machine. I

Referring; more particularly to the drawing made of sections and ioings, 1 represents a base niei'nber which is provided with a track 2-adap d to receive the ice with rollers 5 for Hg in moving the block oiice readily through the sewing machine lvl'ounted upon the base member 1are four columns l formed of hollow piptogether by the usual couplings.The columns or standards are connected intermediate their ends by meansof cross bars 5, t), 7 and. 8. The parallel cross bars 5 are l rovidedwith Tjoints 9 whi adapted to support cross bars 10. l 'he cross bars 10are connected to couplings 11 into which are screwed the vertical guides12. The lower ends of the vertical guides are screwed into couplings 13which are supported by transverse bars 14: and 15. The bars lat connectthe couplings 13 while the outer ends of the bars 15 are screwed intocouplings 16 car ried by the cross bars 8. The transverse bars, as arethe standards 4-, are made from standard piping. A hand wheel 1'? drivesa shaft- 18 which. is mounted in bearings upon the f ame carried by thestandard 4. The shaft 18 car- 'ies a gear 19 which meshes with a rack 20rigidly connected to the frame of a movable carriage which carries thecutters that produce the vertical'slots. V

lhe movable carriage comprises a table 21 upon which is mounted a motor22 having electrical connections through the wires 23 with. the housecurrent. Depending from the table 21 and-mounted in sockets 524; se-

,cured to the bottom of the table are four legs of standard pipeconstruction and braced near their-upper ends by means of transverserods lhe lower ends of these pipes are b aced by means of rods 27. Canricd by the lower ends of the legs are bearings 28. In each pair ofbearings is mounted a shaft 29 carrying a drive pulley 80. Upon theouter ends of the shafts are provided cutters 31 for producing pairs ofvertical cuts in a block of ice. These shafts are driven by pulleys 33rigid with the horizontal shatts'34.

The motor 22 t rough ashatt 35 drives a pulley 36 around whichia belt 37is entrained. This belt is carried around the pulleys 38 and 89., eachone of which being rigid with a shaft 84-. The belt is further entrainedabout a pulley or fly wheel {U mounted in bearings carried by the vol-tically movable carriage.

the post 4 is providednvith a pair of spaced grooved wheels 46 adaptedto support cables 47 which are connected at their lower ends pto aweight lb. The other ends of the cables are connected as shown at 49 tothe lower ends of the legs :25 of the movable carriage. It will be notedthat a shaft 45, a pair of grooved wheels 46 and movable weight 48 arelocated upon opposite sides of the scoring machine.

p The rack 20 is secured by means of an angle bar 50 to the cross bars26 connected to the legs 25 of the movable carriage. A pair of spacedguides 51 are secured to the transverse bars 14 and adapted to receiveand guide a block of ice through the scoring machine when said block otice is riding upon rollers ofthe track 2.

It will be seen from Figure 2 that the legs 25 of the movable carriageare inserted within the vertical hollow guides 12 pro- \iding a hearingfor the legs 25 of the 1novable carriage for guiding the movable carriage vertically when the same is operated.

A. block 5- is secured to one .of' the posts 4 adjacent the dischargeend of the scoring machine upon which are pivotally mounted in spacedrelation a pair of rods or stops 54 and The outer free ends of the rodsare movable in slots formed in a plate 56, which is secured to anopposite standard 4 of the rigid t'rame. Rod 51- is connected by meansof a link 57 to an operating pedal 58 while rod is connected by means ofa link 59 to an o erating pedal (30. These rods are. adapted, when movedin the position shown by the position of the bar 55 in Figure 2, tomaintain the block of ice against movement during the vertical scoring.

Referring more particularly to Figure 3 it will be seen that. thevertical shafts 43 are mounted in U-shaped casings (it which areSll1)1')(.)lt0(,l on the stationary frame by means ot clamps 62. A coilspring 64 is located on each of the shafts 43 between a pulley 4:2 and ablock (35 carried by the upper end of each of the casings (S1. Brackets66 connected with the transverserods 7 of the stationary frame areconnected with the upper ends of the casings (it for aiding in'supporting the same rigidly with resp ct to the stationary frame.

liars (57 have. their inner ends secured to the table 21 aiid have theirouter ends provided with rollers 68 adapted to engage the shaft housings61 when the carriage is moved tor scormg purposes.

The operation of our device is as follows;

wardly. \Vhen the table has been moved to its most elevated position thecone pulleys 41 will be moved into engagement with the cone pulleys 42.The springs 70 mounted upon the upper end of the shaft 433 permit thepulleys 42 a slight upward movement and the springs cushion the shocksof the engagement of the pulleys 41 with the pulleys 42. The motor 22may bein operation or the current may be turned on to operate the motorand since the pulleys 42 are rotated through connection with the motorthe pulleys 41 are likewise rotated, revolving shaft 43 and the cutters44. As the block of ice 52 is moved through the scoring machine thecutters 4A produce a horizontal cut 71.

The block of ice 52 is maintained within a predetermined position withinthe scoring machine by either of the stops 54 or 55, it being onlynecessary to depress either of the foot pedals 58 or 60 to lower eitherof said rods for restricting movement of the block of ice. The block ofice is held by stop 55 to produce the scoring shown in Figure 5. Inorder to vary such scoring the block thus scored is released by stop 55and removed to stop 5- and retained thereby after the cutters have beenoperated. lVhen the cutters are operatively lowered other scorings willbe produced on said blocks spaced from the previous scoring. It must beborne in mind that the stops 54 and 55 are so spaced in actual practice.that they will produce cuts or scorings so spaced that they willrepresent a definite number of pounds which are less than the number ofpounds designated by the scorings on the blocks of ice when said ice hasbeen held by stop 55. As soon as the block of ice is positioned withinthe scoring machine the hand wheel 17 is released and the movablecarriage through its own weight and against the resistance of theweight. 48, will descend slowly and since the motor drives the cutters31 through the belts 3:2, the cutters 31 will produce the verticalscores 72.

It will be seen from Figure 5 that the block of ice normally is soscored that six smaller blocks of 50 pounds each will be provided for.Other scores may be produced by a different arrangement of the positionof the block of ice in the scorii g machine. As soon as th carriagebegins to. descend the pulleys 41 will be moved out of engagement withthe pulleys 42 and the horizontal scoring cutters 44 will remaininactive.
